    iSCSI ZFS block storage options for ESXi with RDMA / RoCE / iSER support

    I'm currently using FreeNAS for iSCSI ZFS block storage for my ESXi server. The FreeNAS box is getting old so I'm looking for a replacement. I'm not currently using any of the other FreeNAS features besides ZFS and iSCSI. I was initially planning to upgrade the FreeNAS box to TrueNAS Core or...

    Ideas for using LVM+BTRFS clone and keeping up to date?

    So this is fun, I just woke up to a clone job of my laptop being finished, it was kind of an experiment. It runs OpenSUSE, so it's got a BTRFS root and snapshots triggered by package manager. I wanted to back it up so I could have a copy of the machine to run elsewhere, here's how I did it...

    ESXi: Do you use NFSv4 or iSCSI for your multipath datastores? What's your stack look like?

    Hey, So I'm wanting to set up some MPIO datastores for ESXi. They'd be for several different workloads: General file storage, video recording on VMs, and the VMs themselves. I looked long and hard at several cluster file systems, but let's face it: Ceph is complicated, OCFS2 is obscure and...

    Tuning ESXi 6.5 (and above) for 100 GbE networking

    I just got my first 100G network set up last night with two Connect-X 5 cards connecting my TrueNAS box to my ESXi 6.5 box. Out of the box, it works acceptably (80 Gbits/sec via iperf2). I've seen some articles that cover tweaks that can be made on the TrueNAS (FreeBSD) side to bring down CPU...

    Occasional OmniOS iSCSI disconnect from VMware

    I use a VM with OmniOS r151024ap and napp-it v. 18.01b as a storage server for a VMware 6.0u3 cluster. Around 30 VMs use 8 iSCSI LUNs for storage. It is mostly very stable, but about twice a year the storage VM stops responding to iSCSI requests from ESXi hosts. After an incident, vmkernel log...

    iSCSI management/metadata server options on a small scale?

    tl;dr -- I need a user-friendly management system for a homebrewed iSCSI SAN for maybe 12-15 machines, on a budget. Suggestions? We've got about a dozen machines on a 40GbE network, and have just finished building a new SAN (20x 8TB drives in two RAID6 pools, so I figure about 100TB of usable...

    Solaris 11 + Napp-IT ISCSI target"differencing disks/child parent"

    I was wondering is there a way to have a "golden image" and multiple child volumes in Napp-it? In Windows Server I used to make one complete install of the OS and programs, create 10 child disks and diskless boot 10 different machines of them using ISCSI. If not, is there anything similar? :)

    Hi all I just started testing iSCSI volumes from my Solaris 11.3 server to my Windows 10 workstation. It's working great, and was super easy to setup. But I am seeing one very confusing thing: zfs list always reports far more data used in the ZFS volume than I have actually created. I...

    ZFS SLOG. Can it be carved out of an SSD volume?

    I have a 960GB S3700 that I'm using as a datastore for VMs (iSCSI) but would like to add a SLOG. Can I recreate the volume on the SSD to use part of it for SLOG and part of it for data? Thanks!
